The BBA242x Paint Mixing Scale with the Panda-EX1P Power Supply Unit is accompanied by the
following documentation:
• Installation and maintenance instructions
• Operating instructions
These installation and maintenance instructions apply to all scales with a type designation containing
the letters BBA242x. The individual model designations may also include numbers detailing the
weighing range and additional letters which indicate special versions.
These instructions contain information for the installation and start-up of the scale and the power
supply unit, as well as all requirements necessary for safe operation of the system. You will find all
information on the weighing applications and the interface operation in the operating instructions.

The BBA242x Paint Mixing Scales are approved for use in a hazardous area classified as zone 1 or
zone 2, gas group IIB and temperature class T4. Then, they are FMRC and CSA approved to the
classification: Class 1, Division 1, Group CD.
The Panda-EX1P Power Supply Unit must be installed in the safe area. If local installation regulations
permit, the power supply unit may also be installed in zone 2. Installation in US Division 2 is not
approved.
The RS232 interface built in the scale is intrinsically safe.
The only peripherals which may be attached are those fitted with an interface having the same
limiting values and approved as intrinsically safe, see section “Technical data”.

If a peripheral unit needs to be connected, its RS232 interface must also be intrinsically safe and
approved to maintain the intrinsic safety.
Ensure that the electrical limiting values of the peripheral match the limiting values printed on the
scale next to the socket.
If this is not the case, install an approved barrier, e.g. MTL 761P.

Turn the scale on its side so that the
connection socket (1) on the bottom is
accessible.
Route the blue cable from the Panda
-EX1P Power Supply Unit to the scale
and plug connector into the scale.
Use a grounding cable (cross-section≧1
mm2) to connect the grounding screw (2)
to the nearest connection of the
grounding system of the building
electrical installation.
Turn the scale back to the proper
Connect the cable from the peripheral
device to the 9-pin I/O socket (3) of the
scale. Fix all connectors by tightening
screws.
